OIL-BURNER.

7 '0 all eohom it may concern:

Be itknown that I, LUKE Toznn, a citi zen of the-United States, residing at Iola," in the county of Allen and State of Kansas,

ence. marked thereon, which form a part of this specification.

My invention relates to oil burners, and

' more particularly to'aburner of thatclass adapted for use in stoves or furnaces, and wherein fuel oil is converted into gas and mixed with air to provide a combustible fuel; the principal object of the invention being to provide a burner wherein the oil.

in operation, and thereby constantly malntain the burner in operative condition, and

obviate the necessity of shutting off the fire when the burner is cleaned.

In the accompanyingdrawings I have illustrated a referred form of structure embodying the features of the invention, wherein:

Figure I is a vertical section of a fire bowl of an prdinary stove or furnace equipped with my improved oil burner; the latter beingsliown in elevation. Fig. II is a similar view with the burner parts in vertical section'l Fig. III is a horizontal section on the line III-III, Fig. II. Fig; IV is a. detailperspective of a. generator. Fig. V is a plan viewof the base plate.

Referring mere in detail to the parts 1 designates the fire bowl'fof an ordinary .stove or furnace, which is here illustrated merely to show the combination and'mounting of my improved burner with a stove or furnace structure.

Seated on av flange 2 which surrounds the grateopening of the fire bowl is a base Specification a ietters Patent. Patented Dec. 23, 1913.

Application med August 18, 1913. Serial No. 785,266.

plate 3 having a central aperture 4, divided by across bar 5 that is provided with a 1 central threaded aperture 6; the upper face of the base having an upturned flange 7 surrounding the central aperture 4.

Seat-ed 0n the base-3 is bowl-shaped member 9 having a base flange 10 located within and confined by the upstanding flange 7 of the base plate 3 and having a.

rim 10 forming an annular chamber 11,

and having an interior wall 12 converging upwardly from the edge of the base aper ture 4 to the top of the body of the bowl.

Located within the chamber formed by the tapered wall 12 is a barrel 13 having a reduced stem 14: threaded into the aperture 6 in the cross bar of the bowl base, and provided with a. T- union 15, having lateral connection with an oil supply pipe 16'and having a plug 17 ,in its lower end adapted for removal when the barrel is to be cleaned; the reduction of the barrel forming a seat 15 whereby the barrel is supported on the cross bar 5.

Integral with the upper end ofthe-barrel 13 are bosses 20 having lower portions 21 adapted for hearing against the inner face of the bowl to space the barrel therefrom and provide a port or mouth through which free air taken in through the bowl base may be delivered for mixture with fuel gas or vapor, and having outstanding upper ends 22-seated on the upper edge of thebowl to space -the generating cup 23, which is formed integral with the barrel, from the top of the bowl 9, and thereby provide'a laterally openipg port between the top of the bowl and the under face of the cup, through which the free air may pass after being delivered frorn'the interior of the bowl.

The generator cup 23 comprises acupped upper face24 communica'tingwith the interior of the barrel 13, anda depending edge flange 25 which is adapted for partially generator cup 23, is a cap 26,1110 base of which is provided with bosses 27 adapted to bear against the upper edge of the cup to space the cap therefrom, and thereby pro vide a port through which the fuel gas gencrate d in thecup may pass, and the sides of which are spaced from the sides of the cup by ribs .28 on the latter, in order that the fuel gas passmg through. the top ports may be delivered downwardly about the generator, the lower edge of the cap being extended below the upper edge of the bowl 9, so that both the fuel gas or vapor and the free lair are'confined together before being released from beneaththe cap, 1n order to ,ecure a suitable mixture of such elements ed cone-shaped coil 33, formed of wire, and

having a shank 34 extended past the top of the bore, where it is provided with a ring 35, whereby the cleaner may be lifted when it is to be removed; the shank 34: being preferably extended through the body of the cone-shaped coil 33 to the base thereof, in

1 order that the coil may be lifted from the bottom and thereby obviate distortion therc of. The cap 26 is also preferably provided with a ring 36 whereby it may be removed from the generator cup by means of a hook, or the like, when the burner is to be cleaned, or for any purpose.

In using the burner, presuming the parts to be constructed and assembled as described, oilis delivered into the reduced portion of the generator barrel and flows up through the bores in the barrel to the cup 24. lVhen the oil is first turned on it rises into the generator'cu and overflows the edges thereof into the owl 11, where it may be ignited to heat the parts and generate vapor from the incoming oil.

\Vhen 'the parts have been sufficiently heated to generate vapor in thecup 24 this vapor is conducted through the annular channel between the cup and cap, and past the port between the cup and the top of the interior wall, where it mixeswith free 'air that enters through the base of the fire bowl and is condut-ted to the annular chamber and within the cap; the mixture of vapor and free air forming a combustible fuel which burns upon delivery from beneath the edge of the cap.'

It has'becn found from experience that most fuel oil contains carbon or solid matter shown, so that the carbon dropping through the generator barrel and cleaner coil will lodge in the bottom of the coil, so that when the cleaner is lifted out of the barrel the carbon is removed therewith.

It is apparent that with the present cons'truction, the cap 26 may be removed and the cleaner lifted from the generator barrel without extinguishing the burner, so that the cleaning may be effected much more easily and quickly than with a burner which it is necessary to dismantle entirely in order to remove the carbon or other solid matter.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters-Patent, is

1. In an oil burner, the combination with a generator, of a supply conduit leading to the generator, and a cleaner located in said conduit, and comprising a cone-shaped coil.

2. In an oil burner, the combination with a generator, of a supply conduit leading to the generator, and a cleaner located'in said conduit, comprising a cone-shaped coil, and

having a shank leading into said generator.

3. In an oil burner, the'combination with a generator ing upwardly thereinto, and a cleaner located within said conduit and comprising an inverted cone-shaped coil, having a shank projecting upwardly through the conduit and terminating in a handle portion within the generator. Y

4. In an oil burner, a generator comprising a depending barrel having a reduced lower portion providing a seat, and a cleaner comprising an inverted coil supported on said seat, and having a shank extending through the barrel into the upper portion of the generator.

5. In an oil burner, a generator comprishaving a supply conduit lead ing a cupped upper portion, and a depending barrel having a reduced lower end forming an interior seat, and a cleaner c0nipris ing an inverted cone-shaped coil of wire supported on said seat, and having a shank extending upwardly and having a ring at its upper end 'locatedwithin the cupped portion of the generator.
